The design of Columbia, MD emphasizes the creation of neighborhood clusters and prior land assembly, which aligns with the town's founding principles focused on community, accessibility, and environmental sustainability. This approach promotes a sense of community and interaction among residents by organizing the town into interconnected neighborhoods.

Prior land assembly refers to the planning strategy used to ensure that large parcels of land were acquired before development began, allowing for cohesive planning and the integration of residential, commercial, and recreational spaces. This method enables efficient use of land and resources, contributing to a well-planned urban environment that fosters social interaction.

The other options mentioned do not accurately capture the essence of Columbia's planning philosophy. High-density buildings and skyscrapers would conflict with the town's more suburban character focused on walkability and livability. Open lots and limited parking might suggest a lack of infrastructure and conveniences that are not in line with the comprehensive community planning seen in Columbia. Finally, a heavy focus on commercial zones and industrial areas would detract from the residential and social objectives inherent in Columbia’s design, which prioritizes a balanced approach to living, working, and recreation. Thus, the correct answer underscores the intentional design strategy that Columbia, MD was built upon.
